摘      要：CONSPECTUS:Two-dimensional sheets,a new family of macromolecules with 2D topology,are posed to rapidly extend material technologies and indispensably shape our *** great expectations of 2D macromolecules urgently call not only a unified understanding of their macromolecular behavior in the new 2D topology but also a general methodology to guide the precise fabrication to achieve disruptive performances of their macroscopic *** by these mutual fundamental problems,we have explored the conformation principle of 2D macromolecules and established a systematic routine for macroscopically assembled materials,in the model of graphene *** Account concludes our recent works in investigating macromolecular conformations and condensed states of 2D graphene oxide and initializes a conceptually new methodology of conformation engineering of 2D *** analogy with classic 1D polymers,we have depicted a systematical conformation map of graphene oxide extending from individual to multiple *** conformation map unifies the theoretic description and experimental observations,establishing the conformation principle of 2D *** have found rich liquid crystalline phases of graphene oxide and uncovered their extremely slow relaxation *** have created a liquid meta-crystal of graphene oxide,a new mesophase state with stable meta-periodicity beyond ordinary molecular order,by the invented shearing microlithography to achieve the free design and control of artificial *** proposed conformation engineering concept has underpinned the versatile design and rational control of multiscale structures of graphene macroscopic materials and promoted advanced performances of graphene fibers,films,and *** conformation principle in the case of graphene oxide can establish a unified theory of 2D polymers after the classic 1D *** conformation engineering will become a useful concept to depict the systematic“fabr
